The Best of Fences

It was a race between man and alien to rule the stars. Scientifically, the aliens were decades ahead—but their real advantage was their incredible elusiveness!
Romm Parmay stepped into the Interstellar Communications Central and eased the door shut behind him.
Nobody paid much attention to him; the five hundred ICC men at the boards were talking in quiet, well-modulated voices that filled the room with a fluctuating murmur of unintelligible sound.
At Number One board, Kerrman was staring moodily at the dead screen, blowing clouds of cigarette smoke at the control panel and watching the smoke writhe and flow down around the pilot lights and switch plates. Parmay walked across the room quietly, and stopped a few feet behind Kerrman.
Boo!
Kerrman jerked, inhaled a cloud of smoke, coughed, and turned around, glaring.
Romm! Dammit, if you weren't my boss, I'd kick you where it would do the most good!
Parmay turned solemnly, presenting his gluteal region for assault.
Go ahead, he said sorrowfully, I'm not the boss any more.
All right, you're asking— what? What did you say?
Parmay turned back to face Kerrman. The grin on his face threatened to break into laughter.
Let you be the first to congratulate me. You are gazing at the Chief of Psychological Contact.
